How Much Is the Average Construction Project Over Budget?

Construction projects around the world are notorious for exceeding their original budgets.

Industry reports consistently show that even well-planned projects in the U.S. can overrun costs by an average of 10–30%, depending on scale, complexity, and unforeseen challenges. 

Research by McKinsey found that large-scale projects can even overshoot budgets by as much as 80%!

An article by leading construction technology firm Propeller Aero cites a comprehensive study spanning 20 countries and 70 years, finding that roughly nine out of ten construction projects exceed their budgets, with an average cost overrun of 28%. 

Similarly, CMiC reported in their How Firms are Preventing Construction Overruns in 2025 article that projects frequently exceed their budgets by 20% to 30%.

And while percentages can feel abstract, the financial impact becomes crystal clear when applied to real construction costs:

• Residential
  In 2024, the Pennsylvania Association of Realtors estimated that building a single-family home cost roughly $428,215, accounting for about 64% of the total price.
• Commercial
  According to leading contracting firm Claris, commercial projects vary widely; for example, constructing a warehouse can range from $165 to $275 per square foot, depending on location and design.
• Industrial
  Costs are also significant for industrial projects, with Cushman & Wakefield's Industrial Construction Cost Guide estimating $142 per square foot for small projects and $85 per square foot for medium-sized projects.

Now consider the overrun: a 20–30% increase on a 200,000-square-foot warehouse can mean an additional $6.6 million to $16.5 million in unplanned costs. For larger industrial facilities, even a modest 10% overrun could quickly add tens of millions of dollars to the budget.

The bottom line: in commercial and industrial construction, overruns aren’t minor hiccups — they’re multimillion-dollar setbacks that can jeopardize financing, delay operations, and erode profitability before the project reaches break-even.

Labor, materials, and compliance often take center stage in construction, but one of the biggest drivers of cost overruns frequently slips under the radar: equipment downtime. Even minor disruptions — like a hydraulic cylinder failure — can trigger significant ripple effects, adding unexpected costs and delays that quickly escalate budgets and derail schedules.

For plant maintenance managers, fleet directors, and operations leaders, recognizing the connection between project overruns and machinery performance is critical. Hydraulic cylinders play a pivotal role in sustaining machine uptime, and when they fail, the consequences ripple through schedules, escalate costs, and ultimately erode profitability.

Although many factors influence whether a project ultimately stays on budget, proactive maintenance and expert repairs make a meaningful difference. By prioritizing cylinder performance, you can reduce downtime, protect schedules, and keep work moving forward.

Why Construction Projects Go Over Budget

Every construction manager knows that even small disruptions can snowball into significant overruns. 

The key drivers we regularly see include:

1. Unplanned Equipment Downtime
   Heavy machinery sits idle when hydraulic cylinders fail, delaying work and incurring labor costs.
2. Poor Maintenance Practices
   Deferred or reactive maintenance leads to cascading failures, forcing emergency repairs or replacements.
3. Scope Creep & Schedule Shifts
   When timelines stretch, operational costs grow exponentially.

Equipment reliability is one of the few cost-overrun factors that project teams can actually control. Organizations that invest in preventive maintenance and partner with vendors skilled in fast, precise cylinder repairs are far more likely to stay on budget and keep projects on track. 

The true cost of downtime is often underestimated. Every hour any of your fleet sits idle — factoring in labor, fuel, and lost productivity — can quickly surpass the investment in timely cylinder maintenance on that machine.

The Role of Hydraulic Systems in Construction Machinery

Hydraulic systems are the heartbeat of modern heavy machinery. They convert fluid power into linear or rotational motion, enabling equipment to lift, dig, and transport with precision. 

Cylinders, as integral components of these systems, directly influence operational efficiency:

• Excavators
  Cylinder failures can halt digging operations, delaying earthwork schedules.
• Cranes & Lifts
  Downtime affects critical load handling and site safety compliance.
• Loaders & Dozers
  Reduced hydraulic efficiency increases cycle times, raising labor and fuel costs.

Even minor cylinder leaks or seal failures can gradually erode performance, causing costly slowdowns. In contrast, fleets that proactively monitor cylinder health enjoy higher uptime and steady project pacing, which translates into more predictable budgets.

Cylinder Failure as a Risk Factor

Cylinders fail due to wear, contamination, or poor sealing, and the impact of that failure includes:

• Immediate Work Stoppage
  Operations halt as affected machinery becomes inoperable.
• Delayed Parts Availability
  Specialized components may take days to source, extending downtime.
• Higher Repair Costs
  Emergency repairs are typically more expensive than planned maintenance, both in parts and labor.
• Cascading Operational Delays
  One machine out of service can disrupt schedules, affecting crews, subcontractors, and project milestones.
• Long-Term Equipment Strain
  Unaddressed failures can accelerate wear on other hydraulic components, increasing the likelihood of future breakdowns.

Top-performing construction firms mitigate these risks by partnering with expert cylinder repair specialists. Vendors like us focus on speed, precision, and long-term reliability, reducing repeat failures and safeguarding uptime. 

Cylinders, Inc. Insight: Treat cylinder maintenance as an investment rather than a cost — quick. Precise repairs minimize downtime, preserve equipment value, and protect project budgets.

The Financial Impact of Poor Maintenance

Budget overruns aren’t abstract — they’re measurable in:

• Labor Costs
  Idle crews still need to be paid.
• Equipment Depreciation
  Machinery sits idle, yet accrues wear and financing costs.
• Opportunity Cost
  Delays prevent additional projects or revenue-generating work.

Research shows that preventive maintenance programs can reduce unplanned downtime by up to 50%, often recouping maintenance expenditures through uninterrupted productivity. 

Specifically, Mitsubishi Electric notes that predictive and preventive maintenance can decrease machine downtime by 30–50% and extend equipment life by 20–40%. Similarly, IBM highlights that proactive maintenance can cut downtime by 35–50% while increasing asset lifespan by 20–40%. 

Hydraulic cylinder maintenance is central to achieving these savings, ensuring equipment reliability, protecting schedules, and preserving fleet value.
